  • 摘要: 生物净化技术在低浓度磷化氢尾气处理方面有良好的应用前景，但磷化氢生物代谢的影响因素、特性等问题未有系统阐述。在生物法处理难溶有毒气体的基础上采用活性污泥体系净化磷化氢气体，探讨碳源、pH等因素对磷化氢生物降解特性的影响。磷化氢生物净化过程中，甲醇为碳源时微生物生长最好，最优C/N为15:1，适宜的pH为6.5～7.5。进口气中PH3浓度高于20 mg·m-3时，微生物的生长开始受到抑制，但生物体内的酶活性明显增强，表明微生物具有抵抗磷化氢毒害作用的特性。活性污泥体系中，PH3去除率最高可达78.0%，生物降解效果明显。
    Abstract: Biological purification technology has a good application prospect in the treatment of exhaust gas containing low concentration phosphine, however the technical parameters and degradation characteristics of phosphine bio-purification have not been systematically investigated. Based on biological treatment of insoluble toxic gases, activated sludge system was introduced to purify phosphine gas, and the characteristics of phosphine biodegradation was investigated in this study. During purification process, methanol was the best carbon source for the microbes to grow fast, the optimized C/N ratio was 15:1, and the suitable pH was from 6.5 to7.5. As the PH3 concentration in the inlet gas was higher than 20 mg·m-3, the microbial growth began to be suppressed, however enzyme activities in the organisms were significantly enhanced, indicating that the microbes have the ability to resist the phosphine poisoning. In the activated sludge system, the highest removal rate of PH3 was 78.0%, presenting a remarkable PH3 biodegradation.
